New DAC or New Streamer or New Streamer/DAC

Acurus: I have the Aries G2 streamer (I do run Roon off a Mac mini for library management) and have found it to be very stable. I’ve yet to have it crash or not find the device.  That said, I’m hooked up via Ethernet as opposed to wireless.  Perhaps that’s the difference.  Or, it could be that some router incompatibility is causing you grief.  I had that issue when running a Bluesound Node 2 wirelessly in this system (before I got the G2).  
It’s possible Lumin is more stable in all environments, but it’s also possible there’s a culprit to your crashes that can be sleuthed out.  I have to say I’m pretty happy w/ the sound of the Aries G2.  I compared it to my Aurender N100H, the Bluesound Node 2, and a lumin mini.  It handily eclipsed all three of those units.
Best,

Thanks for the input. My unit is hard wired as well and I just bought a brand new router (Asus 3100 - high end) so I dont think it can be that. Right now I am having trouble connecting to the mini again after I connected into the Vega G2. Ugh...

What DAC are you using with the ARies G2?

Acurus: I’m using the DAC built into my NAD M12 Pre/DAC.  It’s a decent DAC though I’ll consider an upgrade at some point. 

Best - and good luck.  Wish I could offer a better suggestion as to what the issue might be. 

@cal3713  Thanks. Just read your thread on the Duelund caps. Would dearly love some of those but unfortunately my Tannoys need total 6 caps. Maybe the tweeter series caps someday.

OP good luck with your search.

@lemonhaze Damn, I've seen those duelund based rebuilt tannoy crossovers at "Jeff's place" and yeah, they look super expensive. Thankfully the one cap is my only component.  You can see Nelson pass's  crescendo based tannoy crossovers here: https://jeffsplace.positive-feedback.com/jeff-checking-in-pass-labs-xa25-amplifier-and-the-duelund-a...

Might be a cheaper, but great sounding alternative...

Sorry for the aside folks.
